Overview of Sillimanite Brick

Sillimanite Brick is manufactured from Sillimanite minerals that are subjected to high-temperature firing, transforming into Mullite and free silica. This brick exhibits exceptional properties, making it ideal for high-temperature applications such as glass furnaces, blast furnaces, and ceramic kilns.

Key Advantages

• High Refractoriness: With a refractoriness of 1770 to 1830℃, Sillimanite Brick maintains its stability in extreme temperatures.
• Excellent Thermal Shock Stability: The Mullite structure imparts outstanding thermal shock resistance, minimizing the risk of cracking.
• Low Thermal Expansion: The low thermal expansion rate ensures dimensional stability under high temperatures.
• Corrosion Resistance: High resistance to metallurgical slags and various glass liquids enhances equipment longevity.

Application Areas

Sillimanite Bricks are widely used in:

• Glass furnaces, blast furnace linings, ceramic kilns, and other high-temperature facilities.
• Float glass production line tin bath roof.
• Loading channels, loading equipment, and drawing machines in the glass industry.
